Subject: [PATCH 0/4] efi: libstub enhancements for cmdline parsing and kaslr
Date: Fri, 24 Mar 2017 13:24:06 +0000 [thread overview]
Message-ID: <20170324132410.16628-1-ard.biesheuvel@linaro.org> (raw)
This adds support for the 'quiet' kernel command line parameter, so
that meaningless debug prints can be prevented from corrupting the
boot splash (#3)
Secondly, it enables randomization of the UEFI runtime services region when
KASLR is in effect (#4)
Patches #1 and #2 are preparatory cleanup patches. Patch #4 trivially depends
on #2 which is why they are part of the same series.
Ard Biesheuvel (4):
efi/libstub: fix harmless command line parsing bug
efi/libstub: unify command line param parsing
efi/libstub: arm/arm64: disable debug prints on 'quiet' cmdline arg
ef/libstub: arm/arm64: randomize the base of the UEFI rt services
region
